Question

what is kinetic energy​

Answer 1

Kinetic energy is the energy an object has because of its motion. ... After work has been done, energy has been transferred to the object, and the object will be moving with a new constant speed. The energy transferred is known as kinetic energy, and it depends on the mass and speed achieved.

Answer 2

Kinetic energy:- It is the energy due to motion of the particle known ds Kirietic energy.

Special Points:-

1. Kinetic energy is always positive.

2. Kinetic energy is a scalar quantity.

3. Kinetic ernergy is a relative quantity.

4. It depends on a frame of reterence.

5. If there is no change in the speed of a particle, there will not be any change in kinetic energy. That means work done by the resultant will be zero.
